Abstract
A railway joint without causing vibration is characterized in that the ends of a railway are in a complementary chimeric structure, which can be a clip plane, a V-shaped plane or a tooth form plane, and the mutually chimeric surface keeps in one plane. The advantage of the railway joint is that train wheels can simultaneously press on two railways and pass stably when train wheels run through oblique gap or the chimeric structure, without causing strong vibration or noises, which increase the comfort, promote the train velocity and prolong the service life of the railway. The technology is widely used in railway, subway and other kinds of traffic orbits.
Description
Technical field
The utility model relates to the joint design of rails such as train or subway, particularly a kind of rail joint that can not cause vibrations.
Background technology
Traditional rail is a tack, and its end face is vertically vertical with rail, promptly adopts the tangent form.Consider variation of temperature, rail must leave certain interval when connecting, and actual is discontinuous.Therebetween can't smooth transition.Train is through easily producing strong vibrations and noise.Wheel bump also can cause problems such as the rail leading edge deformation is impaired.
Summary of the invention
The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, and a kind of improved rail joint structure is provided, and makes the smooth transition of rail level energy, avoids producing vibrations and noise.
Solution of the present utility model comprises two rails that connect, and it is characterized in that: the termination of two rails is complementary embedded structure.
The complementary embedded structure of above-mentioned ends of rail can be scarf, V-arrangement tangent plane or profile of tooth tangent plane etc.
The advantage of this rail joint is: can eliminate pressure wheel and cross vibrations and the noise that the rail seam produces, improve the comfortableness of taking.The application life that also helps improving the train speed per hour and prolong rail.Easy construction, originally the mounting means of rail all need not change, and does not increase any new operation.
Description of drawings
Fig. 1 is that the butt joint ends of rail is the vertical view of scarf.
Fig. 2 is that the butt joint ends of rail is the vertical view of V-arrangement tangent plane.
Fig. 3 is that the butt joint ends of rail is the vertical view of profile of tooth tangent plane.
The specific embodiment
Referring to the rail vertical view, the joint of Fig. 1 rail 1,2 is a scarf, rather than traditional positive tangent plane.The gap that the butt end capitiform becomes among Fig. 1 is a R-joining 3, the chamfer angles alpha of rail
1, α
2Complementary.The angle of chamfer of rail is generally 30 °≤α
1≤ 60 °.It is V-arrangement, profile of tooth embedded structure that Fig. 2, Fig. 3 are respectively ends of rail.Chimeric surface keeps same plane mutually.Like this, when train wheel passes through R-joining crack or embedded structure, can be pressed in simultaneously on two orbital planes, can smooth transition.Wheel can not clash into rail end suddenly, therefore can not produce strong vibrations and noise.Present technique extensively is useful for railway, subway and other various traffic tracks.
Claims (2)
1, a kind of rail joint that can not cause vibrations comprises two rails (1,2) that connect, and it is characterized in that: the termination of rail (1,2) is complementary embedded structure.
2, rail joint as claimed in claim 1 is characterized in that the complementary embedded structure of said rail (1,2) termination is scarf, V-arrangement tangent plane or profile of tooth tangent plane.
